The scatterplot above shows the high temperature on a certain day and the elevation of 8 different locations in the Lake Tahoe Basin. The x-axis represents elevation (in feet), and the y-axis represents temperature (in degrees Fahrenheit). A line of best fit for the data is also shown.
Which of the following statements best describes the relationship between elevation and high temperature shown by the line of best fit?
As elevation increases, the predicted high temperature increases.
As elevation increases, the predicted high temperature decreases.
Elevation and high temperature are unrelated.
The predicted high temperature is constant regardless of elevation.
